Mason Natural Collagen 1,500 with Vitamin C

Our assessment

The evidence shows that this product provides a combination of collagen and vitamin C, but the key mineral for bone and muscle health here is calcium. Our assessment: Mason Natural Collagen 1,500 with Vitamin C may support your foundation, but you should understand how calcium in your diet interacts with this supplement. Data not available for the specific collagen or vitamin C levels in this product.

How it works

Think of calcium as a master builder for your skeleton. It supports bone density and mineral deposition, which is critical as you age [NIH ODS]. It also helps your muscles relax and your nerves signal properly [NIH ODS]. If you are taking this supplement for joint or skin health, the collagen component is the focus, but the calcium content may influence how your body absorbs other nutrients.

Safety profile

FDA received 592,059 total adverse event reports for all supplements in this category. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. High levels of calcium in your blood can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS].

Our recommendation

Start by checking your total calcium intake from food and other supplements. You should not exceed the tolerable upper intake level without medical supervision. If you take medications for osteoporosis, thyroid issues, or infections, be aware that calcium can reduce absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Take this supplement at a separate time from those medications. Data not available for the exact calcium amount in this specific product.
